• Bits 7:0 – PCINT[23:16]: Pin Change Enable Mask 23:16
Each PCINT[23:16] bit selects whether pin change interrupt is enabled on the corresponding I/O
pin. If PCINT[23:16] is set and the PCIE2 bit in PCICR is set, pin change interrupt is enabled on
the corresponding I/O pin. If PCINT[23:16] is cleared, pin change interrupt on the corresponding
I/O pin is disabled.
• Bits 7:0 – PCINT[15:8]: Pin Change Enable Mask 15:8
Each PCINT[15:8] bit selects whether pin change interrupt is enabled on the corresponding I/O
pin. If PCINT[15:8] is set and the PCIE1 bit in PCICR is set, pin change interrupt is enabled on
the corresponding I/O pin. If PCINT[15:8] is cleared, pin change interrupt on the corresponding
I/O pin is disabled.
• Bits 7:0 – PCINT[7:0]: Pin Change Enable Mask 7:0
Each PCINT[7:0] bit selects whether pin change interrupt is enabled on the corresponding I/O
pin. If PCINT[7:0] is set and the PCIE0 bit in PCICR is set, pin change interrupt is enabled on the
corresponding I/O pin. If PCINT[7:0] is cleared, pin change interrupt on the corresponding I/O
pin is disabled.
